Cremeplay

About

Most YouTube Music desktop players run on Electron or heavy web wrappers. They consume 400 MB to 800 MB+ of RAM, render unnecessary video decoders and Canvas layers when you just want audio, and accumulate memory leaks over extended playback sessions.

Cremeplay is an ultra-lightweight, high-performance desktop music player built with Tauri v2 and Rust. It replaces the Chromium audio pipeline with a native Rust audio engine powered by rodio and Symphonia, routing raw audio directly to Windows WASAPI with a minimal private working set of ~60 MB RAM on tray and ~150 MB on an open window.

It talks directly to YouTube Music's Innertube API through asynchronous Rust services, providing authentic music discovery, radio recommendations, and library management without Google Polymer overhead or background tracking bloat.

Features

Extreme low memory profile: ~60 MB RAM on tray and ~150 MB with the window open, backed by proactive working-set trimming.
Single-process hierarchy: all WebView2 child and rendering processes are bundled into a Windows Job Object directly under the parent Cremeplay — no orphan processes.
Native audio engine: tracks are downloaded, decoded via Symphonia, and streamed straight to WASAPI with zero video decoding overhead.
Authentic YouTube Music algorithm: full feed exploration including Listen Again, Daily Discover, From the Community user playlists, and Similar To artists, with smart Up Next queuing.
OBS Tuna integration: a built-in broadcast server on http://127.0.0.1:1608/ serves live track metadata and album art to streaming overlays and desktop lyric tools like LyricReme.
Dynamic album-art theme: extracts vibrant dominant tones from the current cover art to ambiently tint the interface in real time, alongside handcrafted dark themes.
Native SponsorBlock: automatically skips non-music intros, skits, chatter, and video outros before frames are rendered.
Discord Rich Presence: shows the live song title, artist, album art, elapsed time, and duration on your Discord profile.
Playlist & library power: collage covers for playlists without artwork, track shuffling, link copying, search filtering, and Google account login with secure persistent session cookies.
System tray & media shortcuts: full Windows media-key support (Play/Pause, Next, Previous) and unobtrusive minimize-to-tray background playback.

Downloads & installation

Grab your preferred format from the latest release (buttons above, or GitHub Releases):
- Cremeplay_0.1.0_x64-setup.exe — recommended. Fast user-level installer (4.6 MB) that registers Cremeplay in the Windows Start Menu, sets the AppUserModelID, and adds an uninstaller in Settings.
- Cremeplay_0.1.0_x64-portable.exe — zero-install standalone binary (20.5 MB) that runs immediately out of the box.
Run the installer (or launch the portable .exe) and sign in to YouTube Music if you want your library.

Optional — connect OBS Tuna or LyricReme: Cremeplay automatically runs a lightweight Tuna server on http://127.0.0.1:1608/. Open LyricReme or your OBS Tuna overlay to enjoy synchronized lyrics and live stream widgets with zero setup.
